Replanked

Replanked refers to the process of replacing damaged, decayed, or worn wooden planks on a vessel or timber structure with new boards that match the original in material and profile. The term is most commonly used in maritime contexts to describe repairs to wooden hulls, decks, or sterns, but can also apply to other wooden surfaces that have lost thickness or integrity.

In a typical replanking project, the ship's hull is inspected to determine which planks must be removed without compromising the frames. Damaged boards are carefully pried away, and any rotten ribbands or frames are repaired or replaced. New planks are cut to fit the hull curvature and thickness, often sourced from similar species and grain. They are then fastened with period-appropriate fasteners such as copper or bronze nails, iron spikes, or treenails, and caulked to keep water out. Seams are sealed with traditional caulking materials such as oakum and pitch or newer sealants where permitted. After installation, planks may be dressed and finished to match the surrounding surface, and the hull is subjected to pressure tests or sea trials as needed.

In restoration work, replanking aims to preserve historical accuracy while restoring structural integrity. The work requires careful documentation of planking patterns, overlap, and fastener spacing; improper replanking can alter the hull's strength, balance, or hydrodynamics. Modern techniques may employ epoxy consolidants and synthetic fasteners to extend life, but conservators often prefer traditional methods on heritage vessels.

Replanked ships, decks, or structures typically regain original appearance and strength, enabling continued use and preservation of wooden maritime heritage.
